酷東西

趣味知識

Pampadromaeus had 88 teeth in total, with 4 in each premaxilla and about 20 in each upper jaw and lower jaw.1

Its lower leg was much longer than its thighbone, which shows it was a fast runner.1

The name Pampadromaeus comes from the Quechua word for 'plain' and the Greek word for 'runner', because it lived in an open landscape and could run quickly.1

Pampadromaeus had some traits similar to theropod dinosaurs, like a gap between the premaxilla and maxilla bones, and front teeth without serrations.1

This dinosaur is known from a single partial skeleton that includes most of the skull, many vertebrae, and parts of the limbs.1 2

Pampadromaeus lived around 233 million years ago, making it one of the earliest dinosaurs ever found.1 2
